The Polestar 4 is the only major-market production EV designed without a rear glass window, replaced by a roof-mounted high-resolution camera feeding a digital rearview mirror. This design choice means camera-system defects have direct rear-visibility safety implications with no glass-window fallback — a different operational picture than camera defects on conventional vehicles.
Polestar's direct-service model (no traditional dealer network) means service interactions, status updates, and documentation flow through the Polestar app rather than dealer correspondence. The app record is the official service record.
Polestar service technicians' familiarity with the digital rearview mirror system varies by service center and tenure, since the system is unique to the Polestar 4 within Polestar's current lineup.
Software updates affecting the camera system can be delivered via OTA without producing a corresponding entry in the service-center record. The closure of any campaign delivered over the air should be confirmed through the Polestar app rather than relying on verbal confirmation.
